Repowering is a common term among electric utilities that refers to rebuilding power plants by taking an old generating unit out of commission, dismantling it, and building a new, modern one at the same plant. The repowered units are more energy efficient, create less emissions, and increase reliability of the power grid.
The City of Glendale, Department of Water and Power is proposing to repower the Grayson Power Plant located in an industrial area of the City of Glendale. A majority of the facilities located at the Grayson Power Plant, were completed between 1941 and 1977, and are proposed to be replaced with more reliable, efficient, flexible, and cleaner units.
The Project site is located in an industrial area of the City of Glendale at 800 Air Way, Glendale, CA 91201, just northeast of the Interstate 5 and Highway 134 interchange. The site is bounded to the south by the Verdugo Wash and Highway 134, to the west by the Los Angeles River and Interstate 5, to the north by commercial properties and to the east by commercial and residential properties. The site is currently used as the Grayson Power Plant. The Grayson Repowering Project would be located entirely within the existing Grayson Power Plant, an operating power plant.
The Grayson Power Plant, named after the City's first Chief Engineer and General Manager Loren Grayson, has been faithfully serving the electrical power needs of the City of Glendale since 1941. Prior to 1937, the City purchased all of its electrical power from the Pacific Light and Power Company (today known as Southern California Edison). That same year after evaluating the current and future electrical needs of the Glendale community, the City not only entered into an agreement to purchase hydroelectric power from the Hoover Dam Project but also made a decision to establish a City owned and operated steam powered electrical generating facility. Construction of the new facility began in 1939 and the first generating unit went into service in 1941. Since that time the facility has been expanded to meet the growing needs of the residents and businesses in the City and has proven to be an invaluable asset to both GWP and more importantly to their customers. However, over time due to age and normal degradation of the equipment, the reliability, efficiency and cost effectiveness of the facility has steadily and continuously declined. Recognizing the tremendous benefit that locally generated power has provided our City and seeing the long term benefits that would be derived from replacing the existing units not only from an efficiency and cost perspective but also an environmental quality standpoint, the City has embarked on a process for the potential replacement/repowering of the existing facility.
The Grayson Repowering Project is necessary to meet current and future energy needs and to meet the Renewable Power Standards (RPS) mandate. The Grayson Repowering Project will achieve the following benefits:
The City is proposing to replace all the existing generation facilities and their related infrastructure, with the exception of Unit 9, by removing existing aboveground and belowground equipment, and facilities and building new generation facilities. This includes demolishing the Grayson Power Plant Boiler Building, replacing Cooling Towers 1 through 5, and replacing the generation units, designated as Unit 8A and 8B/C. The existing generation facilities (with the exception of Unit 9) would be replaced with a combination of combined cycle and simple cycle gas turbine generation units.
The primary objective of the Project is to replace the aged, inefficient, inflexible, and unreliable generation units at Grayson Power Plant with approximately 260 megawatt (MW) net modern power generation that is efficient, reliable, operationally flexible, and that can easily integrate into the City of Glendale’s power system. This Project would ensure system reliability, balance renewable imports, and meet the power needs of the City in the event that the importing capacity from external transmission lines is not available to serve its load.

The City of Glendale, Department of Water and Power (City) is proposing to repower the Grayson Power Plant (Project), located in an industrial area of the City of Glendale at 800 Air Way, Glendale, California 91201, just northeast of the Interstate 5 and Highway 134 interchange. A majority of the facilities located at the Grayson Power Plant, with the exception of Unit 9 (a simple cycle peaking plant built in 2003), were completed between 1941 and 1977, and are proposed to be replaced with more reliable, efficient, flexible, and cleaner units and related facilities and infrastructure. The City is proposing to replace all the existing generation facilities, units, and their related infrastructure, with the exception of Unit 9, by removing existing aboveground and belowground equipment, and facilities and building new generation facilities. This includes demolishing the Grayson Power Plant Boiler Building, replacing Cooling Towers 1 through 5, and replacing the generation units, designated as Unit 8A and 8B/C. The existing generation facilities (with the exception of Unit 9) would be replaced with a combination of combined cycle and simple cycle gas turbine generation units.
The Project would be located entirely within the existing Grayson Power Plant, an operating power plant. The site is bounded to the south by the Verdugo Wash and Highway 134, to the west by the Los Angeles River and Interstate 5, to the north by commercial properties, and to the east by commercial and residential properties. The approximate coordinates of the Project are 34° 09’ 19” N and 118° 16’ 42” W.
Purpose and Need
The proposed repowering of the Grayson Power Plant is necessary to meet current and future City energy needs and California Renewables Portfolio Standard (RPS) requirements. Pursuant with Senate Bill 350 that was signed into legislation in October 2015, the RPS requires retail sellers and publicly owned utilities including GWP to procure 50 percent of their electricity from eligible renewable energy resources by 2030. The City serves its power system load through a combination of renewable energy sources (both local and imports), non-renewable imports, and local generation. The City system’s single largest contingency is nominally 100 megawatts (MW) based on imported power through the maximum City allocation on the 500 kilovolt (kV) Pacific Direct Current (DC) Intertie (Path 65).
In order to meet retail power load obligations, Glendale Water and Power (GWP) relies on a combination of both local and remote generation, as well as long-term power purchase agreements and spot market purchases from a variety of suppliers throughout the Western Electricity Coordination Council (WECC) territory, including the California Independent System Operator (CAISO). Natural gas for generation is supplied by several sources, which include gas reserves in Wyoming, a pre-paid gas commodity contract, and the daily gas market. Landfill gas for generation at Grayson is supplied via dedicated pipeline from the Scholl Canyon Landfill in the City of Glendale. GWP also uses transmission and generation rights to take advantage of arbitrage opportunities and to transact with counterparties in the wholesale market. As a result of recent state mandates, GWP is becoming more involved in short and long-term markets for renewable energy and carbon allowances. GWP operates within the Balancing Area of the Los Angeles Department of Water and Power.
In June 2015, GWP completed its Integrated Resource Plan (IRP) that identified 262 megawatts (MW) of local generation at the existing Grayson Power Plant site as the best option to meet regulatory requirements for reliability. GWP has proposed to repower the exisiting Grayson Power Plant on the existing plant Site. The Project would replace 238 MW of the existing capacity from the boiler units (Unit Nos. 3, 4, 5) and combined cycle units (Unit Nos. 1, 2, 8A and 8B/C) with more efficient generation. Unit No. 9 commissioned in 2003, would remain. The project would comprise two 50 MW simple cycle units and two 75 MW one-on-one combined cycle units. Unit size is limited so that minimum generation levels would closely match the City's internal generation needs under low system load conditions.The simple and combined cycle unit sizes are also strongly influenced by the City's intent to self-supply spinning and non-spinning reserve and to integrate future renewable resources to meet state regulatory requirements for increasing procurement of renewable energy resources.
The Proposed Biogas Generation Project
Landfill gas is considered a renewable energy resource. Currently this landfill gas is located at an existing Class III nonhazardous landfill that has been accepting waste since the 1960’s. This waste is naturally decomposing and producing landfill gas that includes methane, a greenhouse gas that is combustible and can be put to beneficial use. This will help the City of Glendale achieve the State of California mandate that every utility shall provide a certain portion of renewable energy to their electric generation portfolio. By converting landfill gas to renewable energy the City can receive 100% renewable credit for the energy produced. Currently, the City is blending the methane gas with natural gas to produce electricity at the existing Grayson Power Plant boilers. The City is only receiving 50% credit for the renewable energy produced because the landfill gas is blended with natural gas, which is not a renewable resource. The City will produce and receive 100% renewable credit by installing generation units that can directly burn the landfill gas at the project site. Combusting and producing electricity at the landfill site will enable the City of Glendale to decommission the approximately five-mile pipeline between the landfill site and the Grayson Power Plant.
Currently, the landfill gas is collected at a central location within the project site where it is compressed, liquids are removed, and the landfill gas is piped to the Grayson Power Plant via an underground dedicated pipeline approximately five-miles in length where it is blended with natural gas then used as fuel in the boilers to make steam to generate electricity for the City of Glendale. The Grayson Power Plant is being repowered and the new turbines cannot use the landfill gas as fuel. The landfill gas is constantly being produced at the landfill and there are only two options currently available: burn it in the air by flares or put the landfill gas to beneficial use by using it as fuel for the generation of renewable electricity.

Proposed Grayson Repowering Project Frequently Asked Questions
Are you expanding the Grayson Power Plant?
No, Glendale Water & Power (GWP) is not proposing to expand the Grayson Power Plant. The driving force for replacing the obsolete Units 1-5 and 8* at the Grayson Power Plant is to ensure a reliable electric supply for the citizens and residents of the City of Glendale. A majority of the facilities located at the Grayson Power Plant were completed between 1941 and 1977, and must be replaced.
We are proposing to rebuild substantial portions of the plant by taking old generating units out of commission, dismantling them, and building new, modern units in their place. This process is called repowering. The new repowered units will be cleaner, more energy efficient, and will greatly increase the reliability of the Glendale’s power grid.
* units 6 and 7 were retired several years ago and dismantled. Unit 9 is about 15 years old and will continue to operate.
How is GWP going to pay for the repowering of the Grayson Power Plant?
GWP is proposing to finance the repowering project which has an estimated cost of $500 million, through the issuance of revenue bonds. GWP sells bonds to finance capital projects, and the payments for the GWP bonds are covered by the revenue that GWP receives from its customers based on its rate schedule. The tax revenues that the City receives are not used to pay off GWP bonds. The final cost will not be determined until the detailed design is finalized.
The repowering will not have a significant impact on rates. For example, the cost of generation at the repowered plant will be less (more efficient units burn less natural gas to produce the same amount of energy), and for short-term energy needs, the new units can deliver energy more cheaply than spot market power purchases that must be imported with their associated transmission costs. Additionally, the new units will be able to provide spinning reserve (on-line generation that can respond to losses in supply) more cheaply than purchasing and importing spinning reserve capacity from other sources.
GWP is currently undertaking a cost-of-service analysis that will consider all GWP activities necessary to reliably deliver electricity within Glendale that are funded by rates, including capital projects such as the Grayson Repower. The development of a rate case is currently underway and estimated to be completed in February 2018. This rate case is not a result of the proposed project, rather an analysis of electric rates and the cost of providing and delivering reliable power to customer’s homes.
What if the City does not repower the Grayson Power Plant?
The current units at the Grayson Power Plant are well beyond their useful life. Unit 3 is currently out of service. The remaining units (1, 2, 4, 5, and 8) are all 40 to 70 years old and are not expected to continue running much longer and maintenance on these units is temporary and very costly.
If GWP does not repower the Grayson Power Plant, after Units 1 – 8 are no longer available, GWP sources of supply will be limited to:
These four sources total 287 MW if everything is running (leaving no reserves to cover the loss of one of these sources). GWP’s peak load is 350 MW and occurs during the summer or during a heat wave. This is when surrounding utilities also experience their peak loads as well. GWP would make every effort to purchase additional power to cover shortfalls. However, GWP’s options are limited. GWP’s ties to other electric systems for large power imports are limited to LADWP and what can only be brought through LADWP. If additional sources could not be contracted, then demand would exceed supply and the City would experience rolling blackouts.
In the past LADWP has on an emergency basis provided spot supplies of power to tide GWP over. However, that was at a time when GWP had the Grayson units operating and supplying some amount of power. With no Grayson Units except Unit 9 available to operate, the request that GWP would make of LADWP could be more than they could supply. Thus, GWP and the residents of Glendale would be left in a precarious position.
** A Megawatt (MW) equals 1,000 kilowatts of power.
Is GWP repowering Grayson to generate excess power in order to sell it for profit?
We are proposing to repower the plant to meet the City’s load demand and to ensure that there is a reliable source of power for Glendale. GWP is not repowering to sell energy for a profit. The capacity of the Grayson repower was driven solely by the reliability needs of Glendale and minimizing rate impacts to GWP customers. GWP is a publicly-owned utility and our mission is to provide clean and reliable power to the residents and businesses of Glendale.
Glendale doesn’t need this much power. Why are you building such a large plant? Do we really need this much?
The capacity of the Grayson Repowering Project is driven to reliably serve the needs of the residents and businesses of Glendale. Without the Grayson repowering and after Units 1-8 are no longer capable of running, the available capacity through imports from outside sources and the one newer unit at Grayson Power Plant—Unit 9—is 287 MW.
GWP must have in place sufficient reserve sources of power to cover the “loss of the single largest contingency”. This means that we must maintain enough generating capacity to power the City even if there is an unexpected failure or loss of our largest single source of power. For GWP, the largest single source of power is the DC Intertie line, which transmits 100 MW of power to the City. See image of GWP’s sources of power here. In fact, partial and complete loss of the DC Intertie line has occurred in the past, and some of the outages have been for extended periods of time. In addition, reserves must also be in place to re-establish reserves within one hour. With the loss of GWP’s single largest contingency, the City would have only 187 MW of supply available for meeting its obligations.
GWP’s system load exceeds 187 MW more than 80 days a year. With respect to a peak day, GWP’s peak load is 350 MW (with no allowance for reserve margin) and there would be a shortfall of 163 MW that would have to be supplied by resources internal to the City.
The Grayson Power Plant, once repowered, would add a capacity of 262 MW at average annual conditions (64° F). On a hot day (95° F), that capacity would fall to 242 MW. On the peak load day (100°+ F), the available additional capacity would be slightly less.
With 242 MW available at Grayson Power Plant, the City would have approximately 80 MW remain as reserve capacity. Thus, the Grayson Repower allows GWP to reliably serve Glendale by providing sufficient capacity to cover the loss of the single largest contingency and still meet load, as well as the non-operating reserve that could be started to provide the required spinning reserve.
Additionally, as GWP imports increasing amounts of wind, solar and other variable sources of renewable energy into the City, and as more solar power is generated locally in Glendale, this creates increased fluctuations on the power grid. A steady, constant source of energy such as that from the Grayson Power Plant is needed to balance out (“firm and shape”) the energy so that that a smooth and steady supply of power can be delivered to GWP customers. The old units at the Grayson Power Plant do not have the ability to rapidly adjust up and down to account for variances in solar output, based upon weather patterns on a minute-per-minute basis. Modernizing Grayson will allow us to manage renewable energy flows dynamically, so that energy deliveries will continue to be reliable.
Will GWP install any renewable energy sources at Grayson?
Yes, GWP will be placing solar panels onto the new buildings at the Grayson Power Plant, totaling approximately a ½ MW. GWP also plans to install 40 MW/80 Megawatt-hours (MWh)*** of short-term battery energy storage for regulation purposes at Grayson to reduce short-term cycling of the units. This will be done after the power plant is repowered. GWP is committed to renewable energy and will continue to expand our programs to use more solar and wind power. GWP is a leader within California in supplying carbon-free electricity. In 2016 GWP sourced 64% of the energy it supplied to Glendale from carbon-free sources (compared to 44% for all of California). Glendale is already close to meeting the requirement for 2030 that publicly-owned utilities procure 50 percent of their electricity from eligible renewable energy resources. Today, far ahead of the 2030 target date, Glendale procures 47 percent of its electricity from eligible renewable energy resources. This number will only continue to grow.
GWP also provides incentives to Glendale homeowners to install solar power and has in place contracts for electricity from renewable sources. Currently, there are approximately 1,344 solar systems installed in the City, totaling 12.2 MW. This capacity is “behind the meter,” with only a portion being delivered into the GWP electric system. GWP encourages rooftop solar and solar installations have helped to reduce the load growth within GWP. However, because the State does not allow it to be counted towards GWP’s efforts to meet State renewable energy mandates, this solar generation does not appear in Glendale’s power resource mix.
*** A megawatt hour (MWh) equals 1,000 kilowatts of electricity used for one hour.
Will potable water be used as part of the repowered Grayson Plant?
The Grayson Power Plant would use recycled water for all process and cooling water requirements. The main use for recycled water includes boiler water makeup, cooling tower makeup, turbine power enhancement and cleaning, and NOx control for the simple cycle units. Recycled water would also be used for Unit 9 in place of potable water currently being used. The use of recycled water would eliminate the need for 20 acre-feet of ground water from wells in Glendale and 41 acre-feet of potable water currently being used, which is also water efficient and helps improve the City’s overall water conservation efforts.
California’s cap and trade program requires all power producers to pay a cost per ton of CO2 emitted. Is the cost being underestimated?
The cost of greenhouse gas credits would be incurred by Glendale whenever they use electricity from fossil fuel resources, whether GWP generates it or it is imported over the transmission system. Fossil fuel resources will be required until systems of energy storage have been proven on a utility scale for a utility such as GWP. The operating costs would therefore be incurred either way. Intermittent renewable purchase contracts also include a portion of fossil fuel generation.
Does the Grayson Power Plant sit on a mapped Liquefaction Hazard Zone?
Like much of the Glendale area, the Grayson Power Plant site is located within a liquefaction hazard zone. A site-specific geotechnical study for the repowering project was performed and included analysis of both seismic and liquefaction risks. The geotechnical study included recommendations for project design in conformance with applicable building codes, which include considerations for seismic and site-specific liquefaction hazards.
The site has been the home to the City’s local generation for over 75 years and has been subjected to several major earthquakes, including the Sylmar and Northridge earthquakes. Notably, GWP has been able to restore electricity to its customers faster than any other nearby city or Southern California Edison, in part due to having local units at Grayson that were either already operating or were started up, due to seismically-induced loss of transmission imports.
Why can’t GWP just have solar panels and batteries to power Glendale?
Utilizing solar power alone, whether generated locally or imported, would require a significant storage system to be built to “time shift” enough energy to cover the approximately 65% of the hours that the sun is shining (the 65% value considers the variability of solar energy while the sun is shining). Such a system is would be larger than any projects currently being contemplated or constructed to date, and is estimated to cost significantly more than the proposed project. As with all energy projects, battery storage projects also have ongoing costs, in this case the periodic replacement of the batteries and the efficient recycling of batteries.
If solar power imported over transmission lines (along with other carbon-free imports over those same transmission lines) was relied upon as the source of power, most of it would be consumed during the daytime, leaving little, if any, for charging the batteries. During the evening, when the transmission capacity exceeds the GWP load, solar power is not available. Thus, the batteries would be charged using non-solar carbon-free resources, and if they were not sufficient, then other fossil fuel resources.
For a utility scale solar power plant located within Glendale, a large site would be needed to generate sufficient energy to serve the daytime load and charge the batteries. For each megawatt of solar generation installed, approximately 4 to 6 acres are required. To provide the 262 MW that would be required to replace the units that would be lost at the Grayson Power Plan would require approximately 1,310 acres, or approximately 2 square miles. Such a large space is not available within Glendale.
Rooftop solar is another potential source of solar energy, and GWP provides incentives to Glendale homeowners to install solar power on their roofs. Currently, there are approximately 1,344 solar systems installed in the City, totaling 12.2 MW. Those systems are estimated to generate approximately 16.5 MWh of energy. However, the City cannot count on solar generation on private residential and commercial properties as it does not have control over these systems.
Solar energy sources do not necessarily need to be located within the City’s limits. By freeing up transmission which would occur as the result of the Grayson Repowering Project, it would allow the City to either purchase or own solar outside the City’s limits and transmit the energy into the City’s electrical grid via the existing transmission lines.
GWP is pursuing the Grayson project because the need exists for another source of power to supplement the solar energy that could be utilized, GWP’s transmission import limitations, the necessity to be capable of dealing with the loss of a transmission line, and the need to add capacity as needed due to the intermittency of renewable energy (to balance out and manage the fluctuating power flows), all while still ensuring a reliable supply of electricity.
Can Scholl Canyon be used as a solar site?
GWP partnered with a private developer two years ago to study the possibility of developing a solar project at Scholl Canyon. The developer determined that the site constraints at Scholl Canyon made it unsuitable for solar development. For example, the existing environmental control systems for the landfill are required even for a closed landfill (these systems gather methane gas that would otherwise escape to the environment, a gas that has a global warming potential 21 times greater than CO2). Those systems require continued access, which consequently limits the land available for solar panels. In addition, the landfill is subject to significant settlement, which would take the solar panels out of alignment, as well as complicating the electrical gathering system design, necessitating regular rebuilding and realignment.
Will the repowered plant increase air pollution in the area?
The permitted emissions from the Grayson Repower project will be less than the permitted emissions from the existing Grayson Power Plant.
GWP developed emissions estimates for the Grayson Repower to use as a basis for permitting. The permitting process is based in part on the worse case daily emission and peak season monthly emissions coupled with the need to provide sufficient starts and operating hours for possible contingencies. Even with these conservative estimates, the permitted emissions from the repowered plant would be less than the permitted emissions from the existing plant.
The permitted emissions from the repowered plant would be greater than recent historic actual emissions from the existing plant due to the reduced operations resulting from the declining availability of the existing units. However, the increase in emissions is below the mass emission levels that South Coast Air Quality Management District (AQMD) considers to be significant. In addition, mitigating this concern are two considerations:
Greenhouse gas emissions (CO2) are assessed on a global basis. Greenhouse gas emissions from the project will be offset through the purchase and surrender of greenhouse gas credits to ensure that the total level of greenhouse gasses continues to decline in accordance with California policy and regulations.
Demolition of the existing facility and soil remediation will take 9 months. How are you making sure no contaminants if any are emitted into the air?
During demolition of the existing facility, waste removal plans will be developed and implemented to ensure that no lead or asbestos or other known contaminants are emitted into the atmosphere. Demolition will be done in accordance with applicable federal, state and local requirements. These requirements address containment and handling of materials, as well as a monitoring plan to ensure compliance. These requirements are not specific to the demolition of a power plant; they apply to all demolition work. The contractors we will use are licensed to do this type of demolition and meet these requirements.
